Pretentious fuck whom many people find amusing in a "I'm semi-conscious because its five past fuck-knows-what-hour and hey here's some late night TV - oh this guys funny, but only because my brain is concentrating most of its energy on digestion" sort of way. Characteristics of the Letterman include corny predictable jokes, cabaret music, boringcelebrity guests and a good old wank. Apparently the Letterman likes his studio nice and cold, so when a journalist asked why it was so cold in there some PR person was all grovelling-like "because Letterman likes it that way" - what sort of self-centered fucking bullshit is that? Do you control the fucking atmospheric temperature now as well as the airwaves between 3 and 4 am?

John:"I heard Bob pulled a Letterman with Lisa"
Trevor:"Uhumm...heard that too. Heard he banged her in the meditation room"
John:"Why there?"
Trevor:"Because there isn't a security camera and nobody's ever there"
John:"Aha I see....I would also pull a Letterman with Lisa"
Trevor:"You know it"

I tried to watch jay leno, but i got a real sense of how fake LA is very quickly. I hurried and flipped it to Letterman, who always makes me laugh.
Have you seen his "Will it Float?" skit? It is hilarious!
